The Precision Raceworks Engine Coolant Reservoir Cap is a functional and stunningly stylish way to add a nice touch to any engine bay!

This cap come in three color options so there is always a color that will work for you! Black with Billet, Black with Blue, and the Stealth series (all black).

Many people don't realize it but the OEM caps have a pressure release valve built into them. Often times aftermarket companies don't know this either or just don't care. But our team cares about proper function just as much as we care about the appearance in every product we design. For pressure relief, our caps incorporate the OEM internals, so you get all the functionality of the original caps, ensuring a safe and reliable system in place.

These caps offer superior style and performance-grade components that guarantee a reliable fit every time. Durable billet aluminum construction provides long-lasting protection and dependability that will upgrade your engine bay for years to come.

Other companies make covers that install with adhesive over your factory caps and can come off over time. These caps offer superior style and performance-grade components that replace the factory cap not just cover it up. Durable billet aluminum construction provides long-lasting protection and dependability that will upgrade your engine bay for years to come!

  • Weight: 0.391 lbs
  • Material type: Anodized Aluminum
  • O-Ring Material: Viton
  • Retains OEM Pressure Relief: YES

PLEASE NOTE:

These do require assembly and swapping the pressure relief valves from your old caps to your new billet caps. 

 

Fitment Note

You will need to purchase a different coolant expansion tank cap to use as the donor cap.

          Tough Chewer Approved but Not a Forever Toy
          Flavor Name: Original, Size: X-Large
          I do like this toy for what it is meant to do. It is definitely built for strong chewers and holds up way better than softer toys that get destroyed in minutes. The texture keeps dogs interested and gives them something to really work on, which helps with boredom and can support dental cleaning through chewing. It is one of those “finally something that lasts a bit” kind of toys for heavy chewers. That said, it is not something you just toss in and forget about forever. Like most hard nylon toys, it will wear down over time and should be checked regularly for rough edges or changes in shape. Some dogs will also go through it faster depending on how intense their chewing style is, so replacement will eventually be needed. Girl, this is one of those “it survives the chaos better than most, but you still need to keep an eye on it” situations.

          Clean teeth as well!!
          Flavor Name: Bacon & Chicken, Size: Small
          If your dog is a chewer or just bored, these bones are amazing. All of my dogs love and have loved Nylabones. I consider them a must to give your dog as an outlet to chew when bored or when in need of stimulation. Replace as necessary. I always have a pack on standby.
